Quasar RAT Disguised as an npm Package for Detecting Vulnerabilities in Ethereum Smart Contracts
Socket researchers uncover a malicious npm package posing as a tool for detecting vulnerabilities in Etherium smart contracts.
repeat-string
Advanced tools
Repeat the given string n times. Fastest implementation for repeating a string.
The repeat-string npm package is a minimalistic library that allows users to repeat a given string a specified number of times. It is useful for creating padding, indentation, or repeating patterns in strings.
String repetition
Repeats the '*' character 3 times to produce the string '***'.
"*".repeat(3)
This package is a polyfill for the String.prototype.repeat method as per the ECMAScript 6 (ES2015) specification. It provides the same functionality as repeat-string but also ensures compatibility with older environments that do not support the native .repeat() method.
The pad package offers string padding functionalities. While repeat-string focuses solely on repeating strings, pad allows you to add characters to the start or end of a string to reach a desired length, which can include repeating a character or string.
Repeat-element is similar to repeat-string but is designed to repeat any given element, not just strings. It can be used to create an array with repeated elements, which can then be joined into a string if needed.
Repeat the given string n times. Fastest implementation for repeating a string.
Install with npm:
$ npm install repeat-string --save
Repeat the given string
the specified number
of times.
Example:
Params
string
{String}: The string to repeatnumber
{Number}: The number of times to repeat the stringreturns
{String}: Repeated stringExample
var repeat = require('repeat-string');
repeat('A', 5);
//=> AAAAA
